NITED STATES PATENT OFFICE.

ROBERT WILSON CLARKE, OF VICTORIA, CANADA.

CAN-OPENER.

SPECIFICATION forming part of Letters Patent No. 612,483, dated October18, 1898.

Application filed May 18 1898.

T0 to whom it may concern:

Be it known that I, ROBERT WILSON CLARKE, asubject of the Queen of GreatBritain, residing at Victoria, in the Province of British Columbia andDominion of Canada, have invented certain new and useful Improvements inCan-Openers; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The invention has relation to can-openers; and the object is to simplifythe construction and provide a can-opener which will effectively performits work in an easy manner.

With this object in view the invention consists in the novelconstruction, combination, and arrangement of parts which will behereinafter-more fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective viewillustrating the form of my invention. Fig. 2 is a detail perspectiveview of the can-opener. Fig. 3 is a front edge view. Fig. 4 is a rearedge view. Fig. 5 is a plan and side elevation of another form of myinvention. Fig. 6 is a similar view from the opposite side. Fig. 7 is asectional View on the line X X of Fig. 6.

In the drawings, 1 denotes the blade of the opener having a curvedcutting edge 2.

3 denotes a guide-arm that is integral with a transverse web 4:,arranged above the cutting edge. This arm projects downwardly and is atone side of the blade, and is adapted to slide along the outer edge ofthe can, as shown in Fig. 1.

The back of the blade is provided with an inclined edge 5 and afulcrum-ear 6, which projects rearwardly and outwardly from this edge.The,lower end of the blade is formed with a tapering and sharpenedenteringpoint 7.

8 denotes the handle, secured to the shank of the blade.

Serial No. 681,043- (No model.)

In operation the point of the blade is placed upon the head of the cannear its edge, and by tapping the handle gently the point of the 'bladewill be forced into the top of the can with the fulcrum-ear under saidtop and the guide-arm down along the outside of the can. Now by rockingthe device forward and backward it will be caused to sever the top fromthe body of the can, the cutting action taking place on the forwardthrust of the opener, the ear. acting as a fulcrum during the out tingaction and the arm acting as a guide in the movement of the cutteraround the edge of the can.

As shown in Figs. 5, 6, and 7, I provide a metal handle a, the lower endof which is pro vided with a recess 19 and is formed with the guide 0.The blade of the opener has its shank secured in the recess by a bolt orscrew f. An opener thus constructed is operated in the same manner asthe one above described and can be placed on the market at agreatly-reduced cost.

Changes in the form, proportion,and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

A can-opener with a blade having a curved cutting edge and a taperingentering-point, a guide-arm on the outer side of the same and projectingdownwardly, and a fulcrum-ear projecting outwardly from the back of theblade, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

ROBERT WILSON CLARKE. Witnesses:
